Abstract
A method of operating a spark ignition engine comprises introducing a fuel comprised of a water soluble organic compound and at least 30% by volume water mixed in a homogeneous charge air-fuel mixture. The air-fuel mixture is compressed in an engine having a compression ratio of at least about 16, with such compression ratios including the effective compression ratios arising from precompressing the intake air (e.g., turbocharging). The compressed air fuel mixture is then ignited by a spark or like controllable ignition source.
Claims27
A method of operating a spark ignition engine comprising,
- (a) introducing an amount of a fuel comprised of a water soluble organic compound and at least 30% by volume of water into a cylinder of said engine such that a fuel air mixture is formed, and
- (b) igniting the fuel-air mixture by a spark at a crank angle sufficiently advanced during the compression stroke of the spark ignition engine such that the fuel ignites and combusts, wherein the compression ratio of the engine is at least about 16.
